1. A new and distinct cultivar of Sambucus nigra plant named ‘Eva’ as described and illustrated.

Description:

Botanical classification: Sambucus nigra.

Variety denomination: ‘Eva’.

BACKGROUND OF THE INVENTION

This new invention presents a new cultivar of Elderberry, Sambucus nigra, herein referred to as ‘Eva’. ‘Eva’ is unique in that its leaves combine very dark purple almost black, colour with laciniate shape. ‘Eva’ resulted from a breeding programme conducted at Horticulture Research International, East Malling, West Malling, Kent in England. The two first generation crosses (148 and 149) were made in 1988 between ‘Laciniata’ (unpatented) and ‘Guincho Purple’ (unpatented), and between ‘Laciniata’ and ‘Aurea’, (unpatented). ‘Laciniata’ has green laciniate leaves; ‘Guincho Purple’ and ‘Aurea’ have purple and yellow pinnate leaves respectively. The next cross (391) was made in 1991 between a purple leafed seedling of the former progeny (148) and a yellow leafed seedling of the latter (149). The third cross (595) was made in June 1995 between two seedlings of progeny 391 with laciniate leaves, one with tawny leaves identified as 391A and one with purple leaves identified as 391B. Approximately 200 flowers were hand-pollinated and then bagged for protection until seed could be harvested. The collected seed was germinated and resulted in 39 seedlings being planted out in 1997 for evaluation. Out of this progeny, selection 595-35 was selected as a single plant in 1998 for further trialing on the basis of its dark purple, almost black, laciniate foliage. Selection 595-35 was first propagated by softwood cuttings from the originally discovered plant by the inventor in East Malling in 1998 and planted in trial in 1999. In 2001 it was confirmed as worthy of release under the name ‘Eva’ and in subsequent propagation has been found to remain true to type in successive generations.

SUMMARY OF THE INVENTION

The following characteristics have been repeatedly observed and represent the attributes of the new cultivar. These characteristics in combination distinguish this cultivar from its parents and others cultivars currently available in commerce.

    • 1. The foliage of ‘Eva’ is a very dark purple with purple veins and purple stems. It is darker than ‘Guincho Purple’(unpatented) and similar to ‘Gerda’ (U.S. plant Pat. No. 12,305).
    • 2. The leaves of ‘Eva’ are laciniate whereas those of ‘Guincho Purple’ and ‘Gerda’ are pinnate.

‘Eva’ is distinguished from the female parent 391B in that ‘Eva’ has dark purple leaves.

‘Eva’ is distinguished from the male parent 391A in that ‘Eva’ has dark purple leaves.

BRIEF DESCRIPTION OF THE DRAWINGS

The first sheet contains a photo of a two year old example of Sambucus nigra ‘Eva’ as grown in the landscape in East Malling, Kent, England.

The second sheet shows a close-up of the fully open flowers.

The colour is as accurate as possible by conventional photography.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new cultivar as field grown outdoors in East Malling, Kent, England. The plants were 5 years old. Phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions. The colour determination is in accordance with The Royal Horticultural Society (R.H.S.) Colour Chart of The Royal Horticultural Society, London, England, except where general colour terms of ordinary dictionary significance are used.
